Configuration Prerequisites; Configuring Vpn Instances - HP 10500 Series Configuration Manual

Configuration prerequisites

Before you configure basic MPLS L3VPN, complete the following tasks:
Configure an IGP for the MPLS backbone (on the PEs and Ps) to achieve IP connectivity.
•
Configure basic MPLS for the MPLS backbone.
•
Configure MPLS LDP for the MPLS backbone so that LDP LSPs can be established.
•
Configure IP addresses for CE interfaces connected to PEs.
•

Configuring VPN instances

VPN instances isolate VPN routes from public network routes and routes among VPNs. This feature
allows VPN instances to be used in network scenarios besides MPLS L3VPNs.
All VPN instance configurations are performed on PEs or MCEs.
Creating a VPN instance
A VPN instance is a collection of the VPN membership and routing rules of its associated site. A VPN
instance may not correspond to one VPN.
To create and configure a VPN instance:
Step
1. Enter system view.
2. Create a VPN instance and
enter VPN instance view.
3. Configure an RD for the VPN
instance.
4. (Optional.) Configure a
description for the VPN
instance.
Associating a VPN instance with an interface
After creating and configuring a VPN instance, associate the VPN instance with the interface connected
to the CE.
To associate a VPN instance with an interface:
Step
1. Enter system view.
2. Enter interface view.
3. Associate a VPN instance
with the interface.

By default, no VPN instance is
created.
By default, no RD is specified for a
VPN instance.
By default, no description is
configured for a VPN instance.
Remarks
N/A
N/A
By default, no VPN instance is
associated with an interface.
The ip binding vpn-instance
command deletes the IP address of
the current interface. You must
re-configure an IP address for the
interface after configuring the
command.
